The third anniversary of Princess Diana’s death is not expected to mirror the grief that engulfed Britain after the Aug. 31, 1997, Paris car crash that killed Diana, her boyfriend, Dodi Fayed, and their driver.

Princes Charles and Harry will be at Balmoral in Scotland, and Prince William is away from home on the latest leg of his gap year between school and college.

Diana’s brother, Earl Spencer, plans a solemn day at Althorp, the family estate where Diana was laid to rest.

Flowers will likely be placed at Kensington Palace, and above the Pont d’Alma tunnel in Paris, where the fatal crash occurred.

Meanwhile, Dodi’s dad, Mohamed al-Fayed, will announce a lawsuit to be filed tomorrow in federal district court in Washington seeking records relating to Di, his son and others. He remains convinced the crash was not accidental.
